This paper deals with the voltage and current comparison in single phase SVC compensated transmission line by using PI controller and FUZZY controller. The Static VAR Compensator (SVC) is one of the shunt connected FACTS device, which can be utilized for the purpose of reactive power compensation. FACTS is a technology, which is based on power electronic devices, used to enhance the existing transmission capabilities in order to make the transmission system flexible and independent operation. This paper attempted to design and simulated the Fuzzy logic control and PI control of firing angle for SVC in order to achieve better, smooth and adaptive control of reactive power. Transmission line is simulated using 4π line segments by keeping the sending end voltage constant. The receiving end voltage and current fluctuations were observed for different loads. The complete design modeled and simulated in MATLAB using simulink and simpower system block set. The simulated results of receiving end voltage and current in transmission line compared. The comparison showed that the fuzzy control gives better performance than PI controller.
